Application filed September 23, 1912. Serial No. 721,786.

To all whom it may concern:

Be it known that I, RoBERr'J. OWENS, a

ycitizen of the United States, residing at particularly for `the class of separators known as tanning mills, and'they are'espevaluable whenl such mills 'are to be used for separating wheat from oats. .-"They are also desirable for separating other grains and seedsll The object ofprovide a grain separator having large capacity by means of which different grains or seeds, particularly wheat and oats, may' be readily separated from each other.

The invention consists generally inthe constructions and combinations hereinafter lescrihed and particularly pointed out in the claims.

'tu the `accompanying drawings, forming part mf this specification, Figure 1 is a longitudinal vertical section of. a grain sepai'ator or tanning mill embodying my inventiva, Fig. 2 is a plan view-of the upper hurdle, showing the upper portions of the othersieves and showing my improved sieve cleaner arranged upon the upper sieve, Fig. 3

my present invention'is to sieve and the tail is a partial perspectivel and cleaners of Fig. 7, Fig.

In all lot the drawings 2 represents the frame of the `tanning mill, which is here sho-wn as provided with a feed hopper 3, a longitudinally reciprocating sieve shoe e, a lower reciprocating sieve 5, a tan casing and a fan 7 arranged within the casing 1"` andl adapted to cause a current of air to pa y' through the grain and material as it falls from the upper shoe tothe lower sieve.

The upper shoe is preferably provided with a series of sieves 8, each sieve consistving 'of a-suitable sieve frame 9, and a. perforated sheet metal sieveplate 10. These sieves are mounted in the shoe 4 in the usual way with thevlower end .of each sieve projecting beyond the lower end or' the sir-ve .nextabove it in the manner in which such sieves are usually arranged in tanning mills. 4

The head of each sieve trame is preterably provided with a board or deck 11, and the shoe 11 in which said sieves are mounted, is preferably supported at its upper end by hangers l2, and at its lower end by pivoted supporting arms 13. The lower ends of the arms 13 are preferably connetcd to liars 14 that in Aturn are connected with suitable crank pins carried by the fan shaft 15. This fan shaft carries the fan 7 arranged within the casing 6. The arms 13 are also preterably connected tothe lower sieve 5 by suitrotated the shoe 4 and the lower sieve o,

areeach given a longitudinal reciprocatory movement, said shoe and sieve, however, at all times moving in opposite directions.

The grain from the hopper passes on to the upper cud of the. top sieve in the shoe 4 and the vibratory movement. .of the shoe -tends to cause the grain to work toward the "lower end of the shoe, and during this operation one grain is separated from another by the passage of one grain over the ends of the sieves while the other passes throughrthe sieves on to a. lower deck 16. The grain which 'passes through the sieves on to the deck 1G falls from the lower end of said deck on to a deck located at the head of the lower lsieve 5, and thence passes on to the head end of the sieve 5. As the grain falls from the lower end ot the. deck 16 to the deck at the head ot the'sieve 5 it is subjected to a current ot 'air'troni the fan 7, and the dust and the dirt is blown out.. A pivofed plate 1*.) is preferably arranged at the end of the air-trunk and plate may be i'all through them,

turned to regulate and of air from the said trunk.

The sieve plates in the upper shoe arev 4preferably formed of perforated zinc or sheet metal. The perforations in said sieves are usually of sufficient' size to permit the wheat or short kernels of grain to readily while the oats or-longer kernels can only get through by lturning up endwise. Asmost of the oats will lie fiat up'on the sieve it follows that by using a hurdle of sieves of this character, most of the oats will be' taken out of the wheat. Some of the `oats will, ho-weverfowing to the vibration of the shoe, turn up endwise and go through the perforations with the wheat. Some of. the oats will also turn up' far enough to have their the perforations and they will often remain 'for a considerable period of time in this position. Large kernels ofl wheat will also at times lodge in the perfor-ations, thereby plugging said perfor-ations and preventing other grain from passing through them. For the purpose of preventing the oats from turning up endwise and passing through the perforations, and for knocking down' any oat kernels that get ended up and lodged in the perforations, and also' for keeping the perforations clear of wheat kernels that might lodge therein, or for keeping them clear of sticks or any seeds or material that might lodge in them, I provide preferably upon each sieve a vihratory ,cleaner 'that is rapidly reciprocated back and forth over the surface of the sieve and the movement of which keeps the perforations free and clear of grain or other' things that might l odge in them, and which will knock down any oat kernels that get partially into the pert'ora` tions and which would eventually work through them, and which also, to aflarge eX- tent, prevents the oats from turning up endwise as they pass down over the'sieve. 'This' Cleaner consists preferably of a. series: et

cleaner bai-s or slats 20, arranged parallel to each other, a

preferably 'a distance substantially equal to the width of said bars. The cleaner bars are arranged parallel to each other., and are formed int-o a grid by transverse connect-1 ing bars 2l `which are preferably rigidly nailed or otherwise secured ito the topsof said bars. Each of said bars 20 Ihas prete erably a rounded lower suriface,A and 'A aviso@ .preferably a rounded upper surface,.therelnyf4 giving to each of said bars in cross sectiona' substantially oval form. I ndit important.. to have these barsr of curvedform 'on the under side, so that their line .of/ bearing.A

upon the sieve plate is very; narrow, and @I also nd it desirable to have them o'lE curvedv form on top so that'none o'the grain. or` butv if any falls`v on to the top oef the bars ity will immediately.

material will lodge: thereon,

In Figs.' 1 and 2 of thevdrawings Ihave shown these bars extended lengthwise of the sieves, and- I' conthe preferable.:arrangement. I have also. shown thecbars in/.use upon the lower sieve 5, and in this instance also. I have shown the hars .extending lengthwise of said sieve (see Figs. 5 and 6). In Figs. 7, 8, 9, 10 and 11, l have shown the cleaner bars,`e,\:tending cresswise of` the sieve, Otherwise, except for a slight difference'in' detail of'themeans for reciprocating the grids of cleaner bars, both constructions lare substantially alike. y

In the construction shown in Figs. 1,12

and 4C, in which the grids are reciprocatedEv crosswise of the sieves, Ipreferably connect the top grid by a strap 22, to a hook23 on' the hopper, and I connect the other grids to straps 24, that extend through a post'25 and are held inposition by a rod 26, Whichslides through supports inv the 'post 25 and' through holes in the ends ofthe strapsQs..v` Then to reciprocate the sieves I' secure upon f the frame of the machine in bearings 27 an".

vThis upright is providedb withas many arms` .i

30 'as there are siev'es in the shoe 4.- I have here shown three arms '30 projecting from one side of the upright, and other. A ,short strap 3l is connected tofeach sieve frame and entends over the 'end of one ot the arms 30' and pins 33 extend through the straps and through the arms 8O thereby two from the connecting said straps with said arms.
